Frequently Ask Questions

What Is a PTFE/PFA Lined Pneumatic Actuated Control Valve?

It is a lined globe control valve operated by a pneumatic diaphragm actuator, with PTFE or PFA protecting the process-contact surfaces from corrosive media.

Who Is a PTFE/PFA Lined Pneumatic Actuated Control Valve Manufacturer in India?

Alis Valves manufactures and supplies lined and actuated control-valve solutions for chemical, petrochemical, fertilizer, pharmaceutical, water-treatment and other corrosive industrial applications, with PTFE/PFA-lined configurations and pneumatic actuation options.

Why Is PTFE/PFA Lining Used?

The fluoropolymer lining provides a corrosion-resistant barrier between the process fluid and the metallic valve body.

What Flow Characteristics Are Available?

Common options include: Linear Equal Percentage The appropriate characteristic depends on the process-control requirements.
